Updated over 3 weeks ago

Context


The EDITO MyOcean Viewer is a powerful tool for data visualization and download interface. The EDITO MyOcean Viewer as an intuitive, detailed, easy-to-use interface. It is available on all computers and mobile devices via any web browser. You will be able to browse near-real-time and past marine information from anywhere in the world, download datasets, create maps, videos and gifs and share them!

Its main objective is to let users explore the data available on EDITO, with a focus on Copernicus Marine and EMODnet data, by displaying the products on a map in 4 dimensions (latitude, longitude, depth and time).

Step by Step


Data search

At the top left, you can browse the list of products available by clicking on Add layer. The search for a product can be done by using keywords in the "Free-text search" bar and/or by selecting the type of variable and many other parameters, as time range, area of interest, source of data and more.

Let's select the parameters that best match our search: temperature, Global Ocean, in the present, with daily resolution. The number of products decreases, matching the selected filters. The product that best meets our needs is the Global Ocean Physics Analysis and Forecast. When clicking on its sheet, we have access to the product description: Product ID, DOI, spatial resolution etc.

By clicking on Add to map... under the product's thumbnail, you have access to the list of all the datasets and variables you want to add on the map.

As we are looking for temperature data, in daily resolution, we see the dataset cmems_mod_glo_phy-thetao_anfc_0.083deg_P1D-m where there is the variable sea water potential temperature.

Map navigation

You can navigate around the map by clicking and holding the left mouse button, then dragging the map in any direction: left, right, up, or down.

To zoom in or out, simply use your mouse scroll wheel. If you're using a trackpad, this is equivalent to performing a two-finger scroll gesture: place two fingers on the trackpad and move them downward to zoom in or upward to zoom out.

Map customization

Let's see here how to modify the appearance of the data (1), show settings (2), visualize the data according to a depth (3) and a date (4):

In the layers panel, you can open the layer configurations by clicking on the gear icon:

In this tab, you can change the opacity (1) of the layer, the color map (2), and the minimum and maximum values to consider (3) by clicking on the framed icon on the right.

In the figure below, the download icon (1) allows you to define the request parameters in order to download a subset of the dataset as a NetCDF file (cf. Download section). The information icon (2) shows the product's description page. To change the current dataset for another one present in the product, you just have to click on the layers icon (3):

You can access the general map settings by clicking on the gear icon located above the depth axis in the viewer. This opens a panel where you can customize several aspects of your viewing experience:

(1) Session Management

  • Log in or out of your Copernicus Marine account (see this article).

(2) Language Selection

  • Choose the language for the user interface.

(3) Map & Display Settings

  • Switch between different base maps.

  • Enable or disable display features such as:

    • Toponyms (geographical names)

    • 10° graticule

    • Invalid in situ data (quality flags 3, 4, 9)

    • 3x resolution mode (active only until you leave the page)

    • Colour-blind mode.

  • Change the map projection (e.g., Equatorial EPSG:4326, North Polar EPSG:32661 or South Polar EPSG:32761).

(4) Geometries Settings

  • Automatically add sample graphs to new geometries.

  • Set whether large graphs are shown by default.

  • Enable the display of additional statistics.

  • Set a minimum elevation threshold for graph data (e.g., -1000 m).

(5) Units Configuration
You can now define the preferred units for the following parameters:

  • Length:
    km, mi (miles), nmi (nautical miles)

  • Area:
    km², ha (hectares), sq mi (square miles)

  • Temperature:
    °C, °F, K, or original (as provided in the dataset)

  • Wind Speed:
    m/s, km/h, mph, knots, or original

(6) Miscellaneous Options

  • Always show the layer domain and time resolution.

  • Show the full dataset identifiers.

📌 Note about the basemap: the default basemap has been adjusted to prevent potential misunderstandings or sensitivities related to the representation of international borders, which may be subject to differing interpretations. The main reason for displaying borders is to help users orient themselves geographically. This need will soon be addressed through the addition of major cities on the map.

You can find more information here.

Let's now have a look at the depth axis (bottom right). You can display data by depth using this axis. The up and down arrows on your keyboard allow to navigate by 100 meters increments. The scroll wheel of a mouse allows to select a depth more precisely.

Similarly, you can select a specific date from the time axis at the bottom of the interface.

Data exploration

Now that you know how to display a dataset, let's see how to add objects on the map. Many features are available at the bottom right of your screen where you can:

  • Create a point (1)

  • Create a transect using the line object (2)

  • Create a geographic area of interest (3)

  • Import a geometry (4)

  • Access the general settings of the map (5) (cf. Map customization)

With the "Import" button, it is possible to import a geometry. There are five ways to import geometries:

  • Select a preset geometry available in the collections of the "Presets" (1) tab. Four types of preset geometries are available: Marine Ecoregions of the World, ICES Ecoregions, Exclusive Economic Zones, and Territorial Seas.

  • Retrieve previously imported geometries in the "Recent" (2) tab

  • Import geometries in the WKT (3) format

💡EDITO Pro Tip

Here are examples of WKT lines to import:

  • A point : POINT(3.5 42.1)

  • A line : LINESTRING(0 0, 5 5)

  • A line with multiple connected points : LINESTRING(0 0, 1 1, 2 0, 3 3)

  • A polygon : POLYGON((0 0, 4 0, 4 4, 0 4, 0 0))

  • Import geometries in the GeoJSON (4) format

  • Import geometries in the Shapefile (5) format

Graphs are automatically generated for each created/imported object:

  • A point opens a timeserie, a depth profile and a timeseries as a function of depth

  • A line generates a line average and a transect as a function of depth and geographic area

  • An area generates an area average and an histogram

With these graphics, it is possible to:

  • Adjust axes (1)

  • Export to netCDF (2)

  • Export to CSV (3)

  • Export to SVG (4)

  • Delete graph (5)

  • Add graph (6): you can choose the variables to represent from all your layers

Sometimes, insights can be gained more easily by comparing times series, profiles, etc. directly on the same graph. In order to do this, drag and drop one pin box on top of another to group them:

There is no limit in the number of geometries you can group this way. To ungroup the geometries, click on the Ungroup button:

Finally, to delete a geometry, click on the cross at the top right of its plot window. If you want to free some space on your map but don't want to delete your geometries, you can collapse/un-collapse the plot window content by clicking on the arrow in the top right of the window, and/or drag the window with your mouse to move it out of sight.

💡EDITO Pro Tip
To change the date range of several graphs at the same time:

  • Group the geometries together

  • Select "Adjust axes" to select the start/end dates of your choice

  • Ungroup the geometries

The date range will be modified for all graphs!

Add a variable

We now have access to daily temperature data for our geographical area, date and depth of interest. Let's say we also want to know the speed of ocean currents for the same parameters. The visualization of currents differs slightly from that of temperature.

As seen in Map customization, we can choose another variable from another dataset of the same product Global Ocean Physics Analysis and Forecast by clicking on the layers icon. Here we will pick the variable Sea water velocity from the dataset cmems_mod_glo_phy-cur_anfc_0.083deg_P1D-m.

As for the temperature, we can customize the map colors by clicking on the gear icon. You will notice that a feature has appeared: "Style". It allows to visualize the currents in different ways (solid, solid + vectors, vectors).

Now that we have displayed all our variables, defined the geographical area, the date range and the depth range (only for temperature), we can download the data.

Data download

With the objects you can automatically define the geographical coordinates of your area of interest, in the tab of the layer Download icon.

Just click on Define on map (1) and then click on the object of your choice (point (2), line (3) or area (4)):

📌 Note: of course, you can also choose to fill in the North, South, East and West coordinates manually.

You can also enter the date and depth range you are interested in. As for the geographical area, you can define the date range and depth range by clicking on As in map and then by selecting the date/depth of your choice using the axes on the Viewer.

📌 Note: the data and the graphs are updated accordingly to time and depth axes.

💡EDITO Pro Tip: the geographical coordinates of the downloaded data are not those of the objects, but of the rectangle containing the object, as shown here:

Once you entered the subset parameters, you can directly download the data by clicking on Download.

⚠️ There is a 800 MB size limit when downloading data from EDITO MyOcean Viewer. If the request exceeds this limit, a red warning will be displayed:

Data sharing

All the data opened on the interface can be exported as animations, images and embedded links, clicking on the Share icon:

Where you can:

  • Share the link (1)

  • Save an image (2)

  • Create a video (3) or GIF (c), defining the time interval (a), the step (b), and duration (d)

  • Share the embed link (4)

Discover all the ways to share on the MyOcean Viewer, including sharing a link, saving the image, creating a video or GIF and/or sharing the dataset embed link

There is a built-in export-to-image function. Pan/zoom to your area of interest (the export uses the current map view), click the Share icon, open the Image tab, choose whether to include overlays/legend, then select Download. If you need the underlying data for a geographic subset (NetCDF/CSV) instead of a picture, use Subset and download.

📌 Note: if you download an image or a video, only the layers visible on the map will be exported, not the geometries or their plot windows. As a workaround, we recommend enabling Zen mode (press "Z" on your keyboard) to hide the map tools, and then taking a screenshot.

Data upload

⚠️ This feature is still in beta version.

Last but not least, you can visualize your own data on the EDITO MyOcean Viewer by clicking on the tools icon:

There you can upload your own data and explore it using maps and graphs. When uploading your data on the Viewer, we will convert your dataset to ARCO so that you can use all of the application’s features. Conversion will take between 10 seconds and a few minutes, depending on the size of the file and the current system load.

However there are a few requirements (1):

  • Size and format: files should be in netCDF format (max 2 GB)

  • Grid: spatial dimensions should be called longitude/latitude or lon/lat. Only regular longitude/latitude grids are supported

  • Depth: if present, this dimension should be called depth (pointing down) or elevation (pointing up).

  • Time: if present, this dimension should be called time and meet the CF conventions (e.g. calendar: gregorian, units: hours since 1970-01-01 00:00:00).

📌 Note: time coordinates do not need to be regular/periodic.

Your dataset will be given an unguessable ID, and only you will find it in your Personal Catalogue. Feel free then to use the Share Link function, or to remove the dataset whenever it’s no longer needed.

You have the possibility to store (or not) the uploaded dataset into your bucket (2). To do so, you'll need the endpoint (3), the name of the bucket (4), the access (5) and secret (6) keys. If you wish to, you can also define the prefix (7) and the name of your dataset (8).

📌 Note: the “AI forecast” option is not yet functional.
